<p>A method and system for applying a liner to an underground utility structure is provided. First a layer of epoxy is applied to the interior surface of the host pipe using a machine such as a spincast machine. A dry liner is inverted into the pipe directly behind the coating application at a limited speed and pressure. A drag is set on the inversion equipment relative to the speed of the epoxy spinner unit to control inversion speed. Once the liner is completely inverted the internal pressure of the liner is raised and infused into the uncured epoxy.</p> |
